BigFishGames offers downloads of its Dark Tales: Edgar Allan Poe’s Murders in the Rue Morgue for Windows for Mac for $6.99. Add it to your cart and it should automatically drop to $2.99. (If it doesn’t, apply coupon code “WDDARKTALES”.) That’s tied with our mention from last October and it’s $9 under the lowest price we could find for a retail-box version.
